Subject: Offer the signer back where you'd notice it's missing
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

A remote signer dropped by a reload now says so above the composer, with
a button that reconnects in place — rather than letting someone write a
message and only then be told it can't be sent as them. Failing that it
opens the nostr settings, where logging in again is the fallback.

Every remote-signer login made before sessions were persisted lands in
exactly this state once.
